Can the mods of /r/conservative ban your IP address from reddit? One user prepares a lawsuit against these alleged abuses

Reddit definitely does some IP-bans. But it's automatic and not done by the mods I'm pretty sure. Here is how that looks like. I got this same message on all my reddit accounts.

I have been perma banned on a subreddit. When I used another account that got a week ban on that same subreddit all my reddit accounts got a 3 day site wide ban for ban evasion. I'm pretty sure they did this via my IP-address as I don't even use emails for some.

So I think what Reddit does is that they allow you to ban evade because if you don't get banned again that means your behavior on that subreddit is tolerated now. But if they see you get banned again with an alternate account they presume you haven't "learned" and give you a site wide suspension.
